Attorneys for the Tucson shooting rampage suspect are making another attempt to stop the forced medication of their client at the Missouri prison facility where mental health experts are trying to make him psychologically fit to stand trial.

A federal judge will hear arguments Friday over a request by Jared Lee Loughner's defense team to halt the pychotropic drug medications.

U.S. District Judge Larry Burns rejected a similar request by Loughner's attorneys in late June. The 9th Circuit Court of Appeal halted the medication but later allowed it to resume after prison officials determined Loughner's outbursts there posed a danger.

Loughner has pleaded not guilty to 49 charges in the Jan. 8 shooting that killed six people and wounded 13 others, including Rep. Gabrielle Giffords.

He has been at a federal prison facility in Springfield, Mo., since late May after mental health experts determined he suffers from schizophrenia. A judge ruled him mentally unfit to stand trial.
